The statistics characteristics of typical PD in GIS are obtained based on experimental results of the four PD simulation models detected by the ultrasonic sensor,which include N-Φspectrogram(relationship between discharge frequency and discharge phase spectrogram) and Umax-Φspectrogram(relationship between discharge amplitude and discharge phase spectrogram).
然后在此平台基础上,得到不同类型局部放电超声波信号的发生发展规律,给出信号的统计谱图,包括N-Φ谱图(放电次数与放电相位关系谱图)和Umax-Φ谱图(放电幅值与放电相位关系谱图)。
